TECHNICAL FIELD

The present invention relates to a mobile telephone terminal device,commonly named as mobile phone. More specifically, the present inventionrelates to a terminal device of slender rod-formed pen-like mobiletelephone, referred to as pen-type mobile telephone for short.

BACKGROUND TECHNOLOGY

In recent years, along with the development of mobile telecommunicationtechnology, mobile telephone is increasingly popularized. The user'sdemand on the terminal of mobile telephone, namely the mobile telephone,is increasingly higher. Its main point is to demand the design of mobiletelephone to develop in the direction of miniaturization. Thus, lighter,thinner and smaller is the target pursued by mobile telephonemanufacturers. Therefore, various miniature mobile telephonesincreasingly come out in succession.

For the direct-holding type mobile telephone, if the length of mobiletelephone is too short, it will result in unclear transmitted voice. Andthe width of display screen can not be make too narrow due to thehorizontal arrangement. Both length and width are subject to certainlimitation. Thus it is difficult to design a further smallerdirect-holding type mobile telephone. At present, the minimum size forthe direct-holding type mobile telephone is about 90 mm×45 mm×18 mm.

In order to make mobile telephone exquisite with the earphone andmicrophone of mobile telephone being within the suitable relation ofproportion, the flip-type miniature mobile telephone is invented.However, although the flip type mobile telephone reduces the length, butmeanwhile it increases the thickness of mobile telephone. Moreover, thestructure of flip type mobile telephone is too complex, and it putshigher requirements on the use performance and reliability. Thus thecost is higher, thus it is expensive. At present, the minimum flip typemobile telephone is 78 mm×42 mm×20 mm.

At the present technical level, it is almost impossible to make mobiletelephone smaller. It is an affair daring not to think of making mobiletelephone with size similar to that of a pen. Because it is necessaryfor mobile telephone not only to install display, control button,control key, digit and function key, telephone receiver, and earphoneetc., but also to install lot of mobile telephone's wafer and itsaffiliated circuit, SIM card, cell and other auxiliary elements andparts. In accordance with the conventional circuit design and on thebasis of the traditional way of thinking, it is impossible to makemobile telephone smaller.

To sum up, there exist the following shortcomings for the existingminiature mobile telephone:

1. Due to present design in wafer of mobile telephone and the scale ofits affiliated circuit, it is impossible for the area of internalcircuit to be made smaller.

2. As the digital display of mobile telephone is in horizontalarrangement, at least an 11-bit digit should be arranged for one line.Thus the width of display screen can not be made too narrow. Thereforethe width of mobile telephone should be correspondingly wider, limitingthe contour of mobile telephone to develop in the direction of beingnarrower.

3. For traditional mobile telephone, setting SIM locking socket inhousing for the installation of SIM leads to the difficulty forconventional mobile telephone to reduce thickness.

4. Moreover external cell is installed at said SIM locking socket tocover this SIM card, and external cell itself must possess plastichousing, therefore, the thickness of conventional mobile telephonefurther increases.

5. As the digit key of mobile telephone is in horizontal arrangement,therefore mobile telephone can only be operated in vertical direction.The operation mode is single, and sometimes the use is not convenient.Above-mentioned various problems limit mobile telephone to develop inthe direction of being in slender form.

Referring to FIG. 1, it is shown the front elevation view for contour ofa pen type mobile telephone according to an embodiment of the presentinvention. It can be seen from the figure that a pen type mobiletelephone in accordance with the invention includes housing 1, display2, button 3, operating key 4, digit and function key 5, telephonereceiver 6, and earphone 7, which are needed by terminal of mobiletelephone. What is different with terminal of conventional mobiletelephone is that the pen type mobile telephone possesses slenderrod-form and small volume; easy to insert into pocket. In accordancewith the embodiment, concrete size of housing 1 is: length 140 mm×width35 mm×thickness 23 mm; Ratio between length and width is more than 4:1.In addition, hang buckle 10 is installed at its top and back (refer toFIG. 2), so as to be convenient to hang in pocket, convenient forcarrying like a pen.

Referring to FIG. 2, a socket 9 inserted with drawer-type SIM card plug& receptacle is set at the side face of pen-type mobile telephone of theinvention. Detailed explanation will be given for drawer-type SIM cardplug & receptacle in the following in combination with FIG. 3. Inaccordance with a kind of expansion for the invention, a laser exit 8 isset at the bottom of the pen-type mobile telephone.

In order to realize the slender rod-formed pen-type mobile telephone,display 2 of the invention is slender and in longitudinal setting,namely the long side is in up and down direction, and the wide side isin left and right direction. Length of the display is 40˜60 mm, whilethe wide side is 22˜32 mm.

In addition, it is allowed to make oblique arrangement for said digitand function key 5, with angle of inclination between 30°˜60, so as toarrange these digit and function keys 5 in the narrow & long area.Moreover, when the user dials, it can be used for operation both invertical direction and horizontal direction, giving the userconvenience.

In addition, the more important is that various function parts interminal of mobile telephone should be installed in the slenderrod-formed housing 1. Moreover it is necessary not only to bring intonormal play the functions of various parts, but also to ensure thequality of call and convenience of use for the entire device. In thefollowing, internal structure of the pen-type mobile telephone of theinvention will be explained in combination with FIG. 3 and FIG. 4.

FIG. 3 shows internal structure of pen-type mobile telephone for theinvention. In concrete terms, it shows structure layout of various partsin front cover 1A.

In reference to FIG. 3, in accordance with internal structure ofpen-type mobile telephone for the invention, it mainly includes: printedcircuit board 11, radio frequency module 12, fundamental frequencymodule 13, SIM card plug & receptacle 14. In order to make circuit morecompact, fine and close, the printed circuit board in the invention usesmore than 6 layer printed circuit board, for example 7 layer or 8 layer,even 9˜10 layer printed circuit board. Width of the printed circuitboard is smaller than the width of the housing 1, namely front cover 1A.The circuit part is mainly divided into radio frequency module 12 andfundamental frequency module 13. The widths of both modules must be lessthan 35 mm.

Through internal use of more than 6 layer printed circuit board,designing the main circuit part into radio frequency module andfundamental frequency module with their width less than the width of theslender and long housing in accordance with the above-mentioned novelstructure layout, the basic aim of the invention is achieved, namelybased on the pen-type mobile telephone of the invention, it is possibleto make its width less than 35 mm, even less than 25 mm.

In order to make the thickness of pen-type mobile telephone for theinvention smaller, less than 23 mm, the invention especially uses anovel drawer-type plug & receptacle 14. It is mainly composed of adrawer-type locking socket 14A and a card fixing device, with a sizeless than 30 mm for length and less than 20 mm for width. The concretestructure and detailed explanation about this kind of drawer-type SIMcard plug & receptacle will not be given here and reference is directedto the not yet published patent application No. 02269510.9 applied forby the applicant. The emphasis here is given to its manner of theinsertion connection. As the patterns of drawer-type side-insertion ordirect insertion and flatwise placement are used to place and fix theSIM card, the body of pen-type mobile telephone in accordance with theinvention can be made narrower, namely the thickness is smaller. This isbecause this kind of inserting and drawing-out of the SIM card from sidelike operating a drawer can avoid the increase of body thicknessresulting from setting and installation of SIM locking socket in thehousing, and therefore it is allowed to install cell inside the housing1. Thus it is allowed to further reduce the thickness of the pen-typemobile telephone. But traditional mobile telephone must use externalcell, because in installing or dismantling the SIM card, it is necessaryto dismantle external cell that covers the SIM card. External cellitself must have plastic housing, thus it cannot but increase thethickness of the mobile telephone.

In order to further reduce the thickness of a pen-type mobile telephoneof the present invention, a pen-type mobile telephone of the presentinvention in accordance with an embodiment uses a built-in cell 19(refer to FIG. 4). Because the built-in cell 19 does not needabove-mentioned necessary plastic housing as an external cell does, thepen-type mobile telephone of the invention can make its thickness verysmall, for example less than 20 mm.

In accordance with the above-mentioned pen-type mobile telephone, saidhousing (1) can be made less than: length 140 mm×width 25 mm×thickness18 mm.

In reference to FIG. 4, the pen-type mobile telephone in accordance withthe invention includes also built-in antenna 17, buzzer 18 in back cover1B. In the figure, reference sign 20 indicates a screw hole forinstallation. It is also the sole screw hole for installation in theembodiment. Installation of the back cover 1B and front cover 1A dependsmainly on coordination between several locking sockets 21 and severalcard catches 22 at front cover 1A to have close combination, andmeanwhile through installation of screw in screw hole 20 to reach thepurpose of firmness.

In reference to FIG. 3 again, the pen-type mobile telephone inaccordance with the invention sets a function expansion area at thebottom of slender printed circuit board 11. In order to realize thefunctions of earphone, charging and data interface etc., amultiple-in-one socket 16 is installed in function expansion area of thepen-type mobile telephone of the invention, and it is a three-in-onesocket in the embodiment. In addition, in the function expansion area15, it is allowed to install vibrating motor 23 for “calling numberdisplay” and/or a laser for a laser pen.
